What experts liked

The glass base is safe for all the usual places (dishwasher, oven, microwave, freezer), but the lids are not. You’ll want to handwash the lids and keep them out of the heat or freezer for best results.

It’s incredibly durable and resistant to temperature.

What experts didn't like

Since glass can be pretty heavy, this box is suitable for teenagers and older kids.

An Overview On Bento Lunchboxes

Did you know you can actually save around $2,400 a year by packing your lunch versus buying one near your office? Lunchboxes are not only an excellent choice when it comes to saving money year-round, but they’re also ideal if you want to consume healthier foods when all you have nearby are fast food joints.

While shopping for the best Bento lunchbox, keep the following features in mind:

Start by examining the materials used to construct the lunchbox. Some are made of plastic, while others are created from an 18/8 food-grade FDA-approved stainless steel. Stainless steel is a good choice, as it won’t rust or stain. If you’re searching for an eco-friendly lunchbox, go with the Itopor Bento Lunch Box, which is actually made from wheat fiber. No matter which material you select, double-check that it’s listed as BPA-free, so you don’t have to worry about toxins leaking into your food.

Determine how many compartments the lunchbox has and whether the lid has a tight enough seal to keep the ingredients separate. Most Bento lunchboxes have three compartments that are designed with proper portion control in mind. They also individually isolate the compartments, so there’s no seepage from one compartment to the other. Other models that don’t offer this can only be used with dry foods.

Consider the size of the Bento lunchbox. In addition to the more traditional size that fits a sandwich and two sides, there are also slim models and models that are made for snacking. The Bentgo Kids Brights Leak-Proof Bento Kids Lunch Box, for example, is small in size and a better choice for packing lunch for children or nuts, cheese cubes and grapes for adults.

Look for any extras that put one model above another. You may find one company offers a complimentary recipe book, while another provides a choice of stylish lids. The BentoHeaven Bento Box Bundle includes a host of extras, such as a set of chopsticks and a set of fun notes. Others have a thermos for drinks and soups and a lunch bag to carry everything in.

The Bento Lunchbox Buying Guide

  • Check the product care label before washing your bento lunchboxes. While some are dishwasher safe, others are not. Depending on the type of plastic used, the lunchbox may be safe for the top shelf of the dishwasher. Of course, it is always safe to wash the lunchboxes by hand with warm water and a little dish soap.
  • Lunchboxes that begin to smell can be deodorized using either white distilled vinegar or baking soda. Both of these affordable grocery items are known for their ability to get rid of unpleasant odors.
  • If you pack a lunch for your child or spouse, consider adding a fun note each day. The note can contain a sweet sentiment, joke, riddle, photo or trivia question.
  • Your bento lunchbox doesn’t have to be used strictly for food. You can also use it to store screws in your workshop or hair accessories in your child’s bathroom. The separate compartments within the box make it a perfect tool for organizing certain spaces within the home.
  • There are several factors that affect the price of bento lunchboxes. These include the materials used to make the lunchboxes, as well as any extra features and products. The BentoHeaven Bento Box Bundle is just slightly higher in price than the Itopor Bento Lunch Box because even though both models are basic, the BentoHeaven has added accessories. You’ll find the Bentgo Kids Brights Leak-Proof Bento Kids Lunch Box is higher in price than the Ozazuco 3-In-1 Eco-Friendly Bento Lunch Box, thanks to its solid construction.
